The answer is a)
<span>0 imaginary; 3 real
proof
f(3)= = 27-20.9+123.3-216= 216-216=0
so f(x)=(x-3)(ax²+bx+c)=0
after doing euclidean division </span>
<span>ax²+bx+c= (x-8)(x-9)=x²-17x+72
and </span><span><span>x²-17x+72</span> = (x-8)(x-9)
so f(x)=(x-3)</span><span><span>(x-8)(x-9)</span>
f(8)= 8^3-20*64+123*8-216=216-216=0
f(9)=9^3-20*81+123*9-216=0

Swing two arcs above and below the radius is not a step used when constructing an inscribed hexagon.
Answer: Option A
<u>Step-by-step explanation:</u>
<u>There are some steps to draw the inscribed hexagonal.</u>
1. You will have to give a circle marked with a center.
2. Draw a circle radius with a straightedge.
3. Keep the compass open on the radius width and place it where the radius and its circle intersect.
4. Bend the arc along the radius that intersects the circle to the left of the originally drawn radius.
5. Keep the compass width same and set it on the new intersection created in the previous step.
6. Continue this process until six points intersections appear in the circle.
7. Connect the six point intersections.
Answer:
142
Step-by-step explanation:
The line underneath the straight angle is a straight line, meaning it is 180 degrees. <em>180-38= 142</em>
